Gravity and Spatial Interaction Models
نویسنده
چکیده
Spatial interaction is a broad term encompassing any movement over space that results from a human process . It includes journey-to-work, migration, information and commodity flows, student enrollments and conference attendance, the utilization of public and private facilities, and even the transmission of knowledge . Gravity models are the most widely used types of interaction models . They are mathematical formulations that are used to analyze and forecast spatial interaction patterns . The gravity model as a concept is of fundamental importance to modern scientific geography because it makes explicit and operational the idea of relative as opposed to absolute location . All things on the face of the earth

Spatial flows and spatial patterns
The misspecification of gravity spatial interaction models has recently been described by the author. The bias in parameter estimates that results from such misspecification appears to produce the 'map pattern effect' or 'spatial structure bias' in estimated distance-decay parameters. A further aspect of the misspecification bias in gravity parameter estimates is explored here. The severity of ...
متن کاملUsing the Gravity Model to Estimate the Spatial Spread of Vector-Borne Diseases
The gravity models are commonly used spatial interaction models. They have been widely applied in a large set of domains dealing with interactions amongst spatial entities. The spread of vector-borne diseases is also related to the intensity of interaction between spatial entities, namely, the physical habitat of pathogens’ vectors and/or hosts, and urban areas, thus humans. This study implemen...

This paper aims at providing new insights into dynaraic spatial interaction and I-O analysis by linking a multiple objective programming approach to stochastic dynaraic spatial allocation models. In this context, a multiple objective optimal control model is designed, which appears to lead to a generalized solution for conventional spatial interaction problems. Next, by using a Wiener (or Brown...
متن کاملSHAPE OPTIMIZATION OF CONCRETE GRAVITY DAMS CONSIDERING DAM–WATER–FOUNDATION INTERACTION AND NONLINEAR EFFECTS
This study focuses on the shape optimization of concrete gravity dams considering dam–water–foundation interaction and nonlinear effects subject to earthquake. The concrete gravity dam is considered as a two–dimensional structure involving the geometry and material nonlinearity effects. For the description of the nonlinear behavior of concrete material under earthquake loads, the Drucker–Prager...
